OIL BURNER.

Application filed. December 22, 1923.

To all wh-0m z't may concern.'

Be it known that we, OscAR BURNS and CARRIE M. Woon, citizens of the United States, residing at Moorcroft, in the county of Crook and State of Wyoming, and Santa Ana, in the county of Orange and State of California, respectively, have invented certain `new and useful Improvements in Oil Burners, of which the following is a specification.

Our invention relates to oil-burners and provides a simple ,and eflicient burner ofI such construction that the oil will be thor? oughly vaporized in -its yflow to the discharge point and will issue at such point in a quickly combustible condition. The invention also provides novel means whereby the flow of vapor at the burning point will be automatically controlled and will be completely cut oil" in the case of a sudden increase of pressure. The invention also provides novel means whereby, in the event of.

some accident or other cause producing an overflow of oil, the flow to theburner will be automatically cut 0H. Other incidental objects of the invention will appear in the course of the following description, and the invention resides in certain novel features which are illustra-ted in the accompanying drawings and willbe particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a side elevation of a burner constructed in 4accordance with our invention; 4 f

Fig. 2 is an elevation viewing the burner at a right `angle to the view point in Fig. 1, and

Fig. 3 is an enlarged sectional elevation, the section being taken on the line 3--3 of Fig. 1. i

In the drawings, the reference numeral 1 indicates the main supply pipe which is equippedwith a `rotary cut-off valve 2 of any suitable form having a stem 3 which is extended laterally to one side, as clearly shown in Figs. 2 and 43. In installing our improved burners, it is the intention to supply fuel and compressed air from a central station and equip the plant employing the burner with suitable storage tanks in which a supply of fuel and compressed air Vmay be maintained. These tanks will be Serial No. 682,177.

connected with the supply pipe 1 .through any convenient fittings, but it will be understood, of course, that the burners may be employed in connection with local storage tanks not connected with a central supply station.

VThe main supply pipe 1 is connect-ed through an elbow et with a lateral branch pipe 5, which branch is connected by a T- coupling 6 with other branch pipes 7 communicating Vdirectlywith the lower ends of conveying and vaporizing pipes 8 which rise vertically from the ends of the branches 7 and communicate directly with horizontal pipes 9. arranged in parallelism and communicating with downwardly extending pipes 10, the said pipes 10 together with the pipes 8 forming a substantially rectangular system of conduits or conveyers whereby the fuel is carried around the burner so as to be exposed to the heat given out therefrom. The lower ends of the pipes 10` are connected by branches 11 similar to the branches 7'and connected by a T-coupling 12 with a lateral feed pipe 13 extending inwardly toward the pipes 7, as clearly shown in Figs.

'2 and 3. Elbow couplings, as 14, are provided to connect the pipes 8 and 9, the pipes 9 and 10 and the pipes 10 and 11.v as will, of course, be understood, and at the lower ends of the pipes 10 screw plugs 15 may be provided so as to facilitate cleaning of the apparatus in the event that sediment should collect in the couplings. The inner end of the pipe 13 is connected by an elbow 16 with a nipple 17 upon which is fitted an ignition pan 18. A coupling sleeve 19 is connected to the upper end of the nipple 17 and provided with a. flange 20 at its upper end. From the upper end of the sleeve 19, a pipe 21 rises and a valve stem 22 `extends entirely through the said pipe, as shown clearly inl Fig. 3, the lower end of the said stem being equipped with a cut-off valve 23 within the coupling sleeve 19 and adapted to abut the lower end of the pipe 21 in the event of some sudden excessive How of oil through the several pipes. 'lhe upper end of the stem 22 is secured in a plug 24which closes the upper end of an outer pipe 25 which extends down around the pipe 21 in spaced re` lation thereto and is equipped at itsv lower end with a liange 30 adapted to rest on the low the ignition pan 18 and a ballior rollingA weight 28 is loose within the saidpan. The pan, as shown clearly 1n Fig. 1, 1s secured upon the valve stem 3 near one endV so that the greater portion of the pan projects to onev side of the stem and consequently an accumulation of oil in said pan will cause it to overbalance and turn to the position shown in dottedr lilies in IFig. 1, thereby rocking the valve stem4 3 and turning the valve 2 to cutoff position so that the flow` of oil will be arrested and the danger of conflagration or other serious damage will be averted. The turning'of the pan and the stem 3 will be accelerated by the provision of the ball or rolling weight 28 which is normally placed yat that end ofthe pan nearer the valve stem, as shown inlig. l. lVhen an, accumulation of oil, however, tends to tilt the pan, the ball will at once roll to the lower end of lthe tilted pan and will hold it in that position so .that the cut-olf'valve 2 cannot be prematurely opened. y

A controlling valve 29 is fitted in the elbow l so that the flow of oil to the burner may be cut olf or'regulated-as desired. By Opening the valve to a greaterY or less degree, a more or less intense flame may be produced at the ignition Ypoint and, consequently, the V intensity of the fire may be easily controlled.

It is thought the operation of the burner will kbe readily understood.. `When itis desired to obtain heat at the burner, the pipe 25 is raised thereby lifting the flange 30 from the flange 20 and, if the valve 29 be then opened, oil will flow through the several pipes and be discharged through the 4lowerend of the ,pipe 25 over the flange 20 into the ignition pan 18. When this pan is filled, the governor lweight 81 and'pipe 25 are permitted to drop and the flow will then be cut off. The oil in the pan 18 is ignited and the flame therefrom will .play uponv the nipple 17 the coupling'l sleeve 19 and the parts above the same so that the oil trapped therein will be thoroughly vaporized and if it be permitted to escape will at once ignite at the lower end of the pipe 25 between the flanges 2O and 30 and will burn in a hot blue flame. When the oil thus supplied to the ignition pan'has been consumed, the pipe 25 is' againlifted and the vapor thenV issuing from the lower end of the same is ignited,

combustion then taking place between the flanges 20 and 30 as long as fuel is permitted to flow through the pipe 5 and the several pipes leading therefrom. As the pressure of theoil in the pipes rises and Vfalls, the weight 31 will be lifted and perolf the flow so that no unvaporized oil willL be permitted to escape. Should there be an r excessive increase in the pressure of the fuel,

the weight will be lifted to suchan extent that the valve r23 will be seated against the lower end of the pipe 21 and the flow ent-irely, cut oli". 1t will be readily notedthatv theL fuel is forced to rise through the pipe 21 and overflow at the upper end thereofwhere itis received within the pipe 25 and'then flows downwardly to and between theflanges 2O and 30. The lower side of the ange 30 is preferablyslightly flaredv so that it will seat lirmlyupon the upper side of the lla-nge 20iand thereby positively cut off the flow when .the burner is not to operate. also be readily noted that we provide a .conveying or feeding pipe at each side of the burner so that the flame and heat generated at the ignition point of the burner will play upon a very appreciable length of pipe and, therefore, when the oil reaches the discharge point-it will be thoroughly vaporized and will quickly ignite so that the combustionv will be perfect and a flame Vof any desired intensity maybe. obtained by manipulating the controlling valve 29. The burner is simple in construction, its parts4 arecompactly arranged, and it is not apt to, get out of order. n
